Credit and capital structure analyst

Main Street fully retires $150M of 2025 senior notes.

Main Street Capital Corporation has redeemed all of its 7.84% Series A and 7.53% Series B Senior Notes due December 23, 2025, for a total principal amount of $150,000,000. The redemption occurred on September 26, 2025 under the existing Note Purchase Agreement, and was executed at 100% of principal plus accrued and unpaid interest.

Retiring these relatively high-coupon notes removes a tranche of fixed-rate debt ahead of the original maturity date. The filing does not state how the redemption was funded or what other liabilities remain outstanding, so the overall impact on leverage, liquidity, and interest expense cannot be fully assessed from this excerpt alone.

Subsequent periodic reports are likely to show the effect of this transaction on interest costs and balance sheet composition as of the reporting period that includes September 26, 2025.
